Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555780, here are decompositions:

13 + 555767 = 555780
19 + 555761 = 555780
37 + 555743 = 555780
41 + 555739 = 555780
73 + 555707 = 555780
83 + 555697 = 555780
89 + 555691 = 555780
97 + 555683 = 555780

Showing the first eight; more decompositions exist.
